Description

Technical Field

[0001] The invention relates to the technical field of medical testers, and in particular to a hot compress bag tester. Background Art

[0002] Hot compress bags have the effects of promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, warming the meridians and dispersing cold, and dredging the meridians. They can increase blood circulation, promote the absorption of inflammatory metabolites, help reduce inflammatory edema, and relieve pain. Hot compress bags are indicated for periarthritis of the shoulder, low back pain, joint pain, sciatica, soft tissue injury, stomach cold, abdominal pain, and dysmenorrhea. By generating heat, local skin blood vessels dilate and become congested, blood circulation is accelerated, and local metabolism is promoted, thereby achieving the purpose of physical therapy and pain relief. In addition, warm stimulation can activate the phagocytic ability of the reticuloendothelial system, promote the metabolism of various substances in the body, and has a good effect on various inflammatory reactions. It can also promote intestinal peristalsis, promote inflammation absorption, accelerate blood circulation, relieve tissue adhesion, and improve local nutrition.

[0003] However, there are some disadvantages in the use of hot compress bags. For example, when making hot compress bags, the temperature of the hot compress bags must be uniform to ensure the hot compress effect. This requires testing after the hot compress bags are completed. Traditional tests heat the hot compress bags and then perform single-point temperature detection on the hot compress bags to obtain the temperature value of the hot compress belt, thereby determining whether the hot compress belt meets the requirements.

[0004] The above test results have the following problems:

[0005] When using a traditional hot compress bag, after the electric heating pad is placed in the hot compress bag, the temperature of the hot compress bag in contact with the human body is adjusted by the temperature control switch of the electric heating pad. However, there is a certain delay in the temperature control device. During the hot compress process, due to the heat preservation effect of the hot compress bag, the temperature of the contact part between the hot compress bag and the human body continues to rise. For some people who are not sensitive to heat, the temperature adjusted by the temperature control device is often too high, which may cause overheating and even burns when removing the hot compress bag, and the effect of continuous hot compress therapy cannot be achieved. Since the hot compress bag is in surface contact, the contact surface temperature of the hot compress bag must be tested, and the temperature value position cannot be detected at a single point. The test result cannot accurately reflect the overall temperature value of the hot compress bag. Summary of the invention

[0055] The specific implementation process of the present invention is:

[0056] Power on the tester, turn on the power, and the display control screen will show the current temperature of each temperature sensor. Put the test heat pack on the workbench, then put the upper cover on the heat pack, and connect the heat pack wiring to the therapeutic device;

[0057] The tester starts working by pressing the button on the display control screen, setting the temperature of the water temperature box, and the main control system automatically turns on the water pump to start the entire water circulation system;

[0059] When the temperature of the thermostatic water tank rises, the temperature of the thermostatic box above will also rise through the effect of the water circulation system. The working temperature of the PVC surface of the thermostatic box is 35°C. Therefore, through the third temperature sensor of the thermostatic box, the main control system knows the current temperature of the thermostatic box, thereby controlling the water flow rate of the water pump to keep the PVC board surface at a constant temperature of 35°C.

[0060] When the surface of the PVC board reaches a constant temperature of 35°C, in order to test the environment of the hot compress bag, turn on the hot compress bag function of the therapeutic device and let the hot compress bag work for 15 minutes to allow the hot compress bag to reach a stable state. According to the corresponding temperature curve displayed on the display control screen, it can be seen that the temperature difference of the 5 points can be seen, and then it can be judged whether the temperature uniformity of the hot compress bag meets the requirements.
